Solve the problem.f(x) =  is defined on the interval . In (a) and (b), approximate the area under f (to three decimal places) as follows:(a)Partition  into four subintervals of equal length and choose u as the left endpoint of each subinterval.(b)Partition  into four subintervals of equal length and choose u as the right endpoint of

each subinterval.(c)Use a graphing utility to approximate the actual area A.
